Cleaning a old tonearm


Hi, A friend gave me an old Grace 727 tonearm and it is very dusty and dirty from sitting out in the open. My question is how and what should I use to clean it. I do not want to mess with dissasembleing the bearings. The dust seems to stuck to it and will need some type of cleaner. Or is this a lost cuase? Thanks in advance.

Pledge Multi Surfaces is a new product designed to clean metal, wood, glass and electronics. It claims to be streak-free, anti-static, and leave no residue. I used it to clean a TT that I am restoring, including the aluminum tonearm, and it worked so well I went on and used it to clean all my equipment. It is clear, has little order, dries quickly, and the dirt is quite visible on the mirofiber cloth. I got it at Wal-Mart for $3.97 for a 9.7 oz aerosol can. Feels like a commercial, but this is very different and more effective than other cleaners I have used.
Agree that cleaning will not be a problem. Any good degreaser/cleaner will work. Just ensure you rinse and dry effectively.
If you use lighter fluid or other hydrocarbon solvent, use outdoors or w substantial ventilation AND make sure you dispose of surplus properly; i.e., not on ground out back or down the drain.
WD-40 leaves a gummy residue. I would not characterize it as a cleaning product and I would never use it on any piece of audio equipment.

Q-tips and alchohol work for me. My used TriPlanar was not only dusty when I received it, it was coated from end to end in silicone damping fluid. Yuck! (The seller failed to empty the damping trough before boxing it up - lazy or stupid, your choice!)

It took me 4-5 hours to clean it (the TP has a lot of parts, many more than a Grace) but I look on that as time well spent. I got to know the tonearm intimately before I even mounted it. That knowledge has repaid the effort it took to gain it many times over.
